Application Insights

Visual Studio Application Insights is a flexible analytics service. It helps us to get the insights of performance and usage of an application. It can be used for .NET- or J2EE-based applications that are hosted on-premise or in the cloud. We will cover only a few important features that come with this service in this book.

Create a sample application and go to its MONITORING section. Click on Application Insights. Select Create new and click on OK:

We can create a web test for testing the availability of applications from multiple regions. We can select a ping test or multi-step test to check the availability. The alert criteria can also be configured.
Performance testing is also a very interesting feature available in App Insights. It is more of a load testing based on the number of users for a specific duration.

We will see the how to of both in this book where we intend to cover monitoring.
